a = -5 ;
b = -1.670000000000000 ;
r = (b-a).*rand(1000,1) + a;

is there any way to generate only one negative random no
like there is function for positive nos randi that generates one random no from a given range

Ran in:
The randi function generates random integer values in a specified range. Nothing about the function limits it to only being able to produce random positive integer values.
allPositive = randi([2 10], 1, 5)
allPositive = 1×5
5 9 2 6 3
●
allNegative = randi([-10 -2], 1, 5)
allNegative = 1×5
-4 -6 -2 -9 -5
●
mixedSigns = randi([-6 6], 1, 5)
mixedSigns = 1×5
-2 1 6 0 -3
●
If you want to generate normally distributed or uniformly distributed numbers, see the documentation pages for the randn and rand functions respectively.
